Williams chief operations engineer Mark Gillan insists that nobody within the team can be happy with its current level of performance after another race without points at Suzuka.

Pastor Maldonado and Rubens Barrichello could only manage 14th and 17th in the Japanese race as Williams' wretched season continued, with the team losing out through the safety car period and finishing outside the top ten once again.

"Nobody in the team is happy with the current performance of the FW33, and this weekend's race in Suzuka was no exception," Gillan said. "This was my first race in charge at the track and I'd like to thank the race team for their excellent effort and dedication throughout the weekend."

One bright point for Williams was the fact that Pastor Maldonado's fastest lap during the race matched that set by Lewis Hamilton, although Gillan insisted there was still a lot for the team to do to ensure more performance next season.

"Pastor's race balance on option tyres and low fuel during the last stint was reasonable but it is clearly evident that the overall pace of the car needs to dramatically improve and this is what we are all working hard to achieve," he said.

"It will not be an overnight improvement but we do aim to see a steady continuous improvement and an integration of better processes through the remainder of this season and into next."
